Why ROCKWOOL?
It withstands over 1,000°C and adds no fuel to a fire.
Stone wool lets moisture escape, so your home stays free of damp and mould.
On a quiet road, it redefines what quiet means.
Warm in winter and cool in summer.
Stable for life. Stone wool does not sag, shrink or settle.
Peace of mind
Designed for your home and independently verified. Over 500 TrustMark jobs, with zero remediations required.
Park home specialists
Park homes call for detailed, careful work, and our teams love it. Few jobs bring a bigger transformation. With ROCKWOOL, its walls become non-combustible for the first time. Your park home is transformed: warmer in winter, cooler in summer and quieter all year round.
Loft insulation
Heat rises. A well insulated loft keeps it in your home. We lay mineral wool across the loft floor, neatly and with care, and leave the space clean.
Award winning, year after year
Eight consecutive Greater London Energy Efficiency Awards, 2019 to 2026. Winner, Small Scale Project, South East 2026.
Accredited and independently verified
We insulate your home with ROCKWOOL, the world leader in stone wool. Non-combustible, with the top A1 fire rating. Breathable, so your walls stay dry. Your home is quieter, warm in winter and cool in summer.
In 1958, ROCKWOOL was fitted to an aircraft hangar at Copenhagen Airport. Tested 65 years later, it insulated as well as when it was new.
In their own words
“The thing that we noticed first was the silence. It’s so quiet in here and… sleeping is so much better.”

Sian and Pete’s cold, damp 1930s home won Small Scale Project, South East Energy Efficiency Awards 2026. Cotality verified our work independently and published it as our joint case study.
One home, twelve trades
Insulating a home touches everything on the outside, and a few things on the inside: windows, gas, electrics, pipes, gutters, lead flashing, rooflines, damp proof course, fences, scaffold, insulation and render. Like any specialist work, it requires professionals with the right experience. Every step has to be right before the insulation and render cover it. Our team has insulated over 500 homes, with zero remediations required.
Our team holds every registration shown above, so each step is done to its own standard, in the right sequence.
TrustMark registered
External wall insulation since 2012. Today, nine TrustMark registered measures, planned together for your home.
A cold, damp 1930s house, insulated in a little over a week. Catherine worried about the look until she saw our other homes: “They all looked fabulous.” Her verdict now: “It has a much cosier feel about it.”
Award winning, year after year
Fitting the insulation is half the job. Pipes, electrics, windows, rooflines and fences all need adjusting so the insulation sits perfectly. That is the part we excel at.
External wall insulation on the side, with brick slips on the corner to match the brickwork. The front is ready for internal wall insulation, as a possible second phase.
Character kept
We set out to keep the character of every home we insulate. Often it looks better than before we started.
On every job we look after the details: bay windows, brick quoins, decorative bands and sills. If a feature can stay, it stays. If it can be recreated in the new finish, we recreate it.
Some homes have intricate brickwork that is hard to replicate. Others are in conservation areas or are flats. For these, internal wall insulation could be the right choice. We can work with you to find the best solution for your home.
We do the job once. We do it properly.
Every team member on your job is hand-picked and trained by us. Well looked after, with years of continuity, and it shows in the work.

Getting your Building Regulations certificate is part of our job. When you sell your home, the buyer’s solicitor will ask for it.

We carry industry-leading levels of insurance cover, so your home is protected at every stage of the work.
